Blas as you know I have been in aviation for many years----all modern jet airliners are bottom fueled to eliminate the static discharge associated with free fall fueling----
And this is after grounding the aircraft to ground rods thru the ramps, grounging the fuel trucks, and then grounding the truck to the aircraft--
Back to a car---a static charge will build up on your car driving along ( if fact, the lamans filler at high driving speeds can build up quite a charge from the air flow around it), now you stop for gas---your charge gets transferred to the pump, along comes another car, ditto, ditto again and again----then comes a tanker that got a big static charge filling up at the refinery after a tunderstorm, drove 600 miles to the station and goes to offload his fuel-----there has been enought differential charge built up to ignite the truck--- do you want to be there?????
Bond the filler to the tank----someday it could save your life
